Home made weed killer

[Ekphrasis]

Has anyone used a concoction of vinegar, salt and washing up liquid for weeks on a path/ drive?

Is it ok to use (a bit more eco)?

Does it work?

I've got ecover washing up liquid.

It will work. Ecover should work as the purpose of the washing-up liquid is to help the salt water be absorbed by the plants. The salt will stay in the ground for a while making it difficult for other plants to grow. But it may also leach into the surrounding ground and kill off anything that's growing there.

I'm not sure it's any more eco-friendly than the products you can buy at the garden centre. They all kill plants and lurk in the soil to prevent more plants growing.

But I guess at least salt and vinegar are more biological than a chemical?

Vinegar is acetic acid and salt is Sodium Chloride. They're both chemicals.
A biological control would be an animal that ate them or something. A shop-bought path weedkiller would have something like glyphosate in to kill the weeds and then another chemical to stop fresh weeds germinating. But it's all chemicals - just some you can also sprinkle on your chips - not glyphosate obviously

True! I guess I mean relatively safer for pets and children! And maybe cheaper?!

Salt and vinegar may be cheaper initially but I'm not sure how many times you'd have to apply it. [This is making me want crisps].
I guess it might be safer if your children and pets were prone to picking up stones from your drive or licking them or something

I've killed weeds in our patio with vinegar. I don't want anything more "dangerous" than that in our garden. Most weedkillers are toxic.

I use boiling water from the kettle on the patio weeds like Monty Don. It is very satisfying and no residue.
